    Hello,

    Simply I want to satisfy on:-

    1. Whether any information can exist just as wave/energy or otherwise also in real sense? Can energy be non-kinetic or stable?

    2. If not, whether so considered Potential energy is real energy or just potential to get energy?

    Say a wood, it is said to have potential energy of burning. But I think, it has poential to energy not energy in itself. To get energy from woods(all matters) I think other/outside aids are also needed eg. O2 & fire for burning wood. As such, how potential energy is energy in wood?

    Best wishes.

    a rock falling from heavens, send by angels of our beloved God, has a potential energy as it falls. Its kinematic energy increases as it approaches the land of our birth Earth and finally its potential energy decreases and comes to null as it hits the ground dark and poisoned with blood from wars of Eden.

    Angel in motion has potential energy. Angel at rest has potential to energy. Unless the Angel has fallen from Eden and lays on ground lifeless, of course it would be an Archangel...wings covered in dust and shadows of mountains of apathy surrounding the once servant of God.

    Welcome & thanks.

    If it is energy(potential) in real sence, can enegy be stable? Is so called potential energy is real energy or just a memory by structural or motion changes in any substance?

    A matter is made up of energy & is capable to be converted in to energy. Then why it is not called energy or condensed energy instead of matter?

    Angel in motion may have both kinetic energy & potential to more enegy if not landed. But how such potential to energy is energy in true sense?

    Please tell about outside aid is needed for potential energy to be converted in true energy eg. O2 & ignition to get energy from wood, gravity for a falling substance etc.? If it is energy, outside need may be unnecessory? Whether outside aid is needed for energy or kinetic energy?

    because matter is energy at rest and since we live in a world of matter we use it more often as such.

    Is it not correct in true words that we live in a world of condensed energy along with energy?

    Whether signals in electronics are kinetic or can also be stable?

    The question "what is information" is one that still appears to be being answered.
    If you are doing physics information is correlation between "systems" which are "separated" by space and time.
    If you study computational science, information is data and programs are things that change the information in data (cells).

    The signal domain, electronic signaling in particular, is open because the spectrum is. A signal is really just a correlation in space and time; it can be a lot of things. For instance, genes in DNA are considered as signals by geneticists, forensics uses "fingerprinting"... it's an extremely broad subject that means different things in different spheres of thought.
     
  13. 1. a. yes e.g. a sound wave. b. I don't know what you mean by stable in the sense of energy but as far as non-kentic the answer is yes but only through telepathics.
    2. potential energy is real energy because it is the enrgy to do things.

    High pressure gas in a tank has the ability to do work, but it's not energy, per se'. However, it's temperature is the kinetic energy of its molecules.

    A ball on a hill has "potential energy." It's not energy, per se'. It merely has the potential to do work, as does the high pressure gas in a tank.

    Telepathics?
    You wouldn't be talking nonsense would you?

    A radio receiver also has capacity to receive, process & express radio sibnals. How it can be said as energy? By stable energy I mean non-kinetic (if potential energy).

    I am not sure whether potential energy is really energy or just potencial to energy?

    In this sense, I don't know brain memory get signals/waves from where--from inside body or from outside?

    That is the point. A matter has potential energy to be converted into energy but not real energy.

    In this sense, will brain or its memory not just be a potential energy or matter with specific strucural changes? As such where is true energy which is recieved, processod or expressed?
     
  18. ok then with current science non-knetic energy being potential energy is impossible.

    What?
    A ball held in the air is full of potential energy.
    And potential isn't kinetic.
    What about chemical energy?

    What do you mean "current science"?
    Are you suggesting there'll be any science to telepathy?

    Sorry, are you telling or asking?

    Can so called potential energy be taken as memory of substance in real sense?

    A question will arise. Can energy be non-kinetic?

    All substances look to be relted/connected to each other. Are they not?

    Can't we say that ball in air has full of memory of energy?

    As such, can we just consider potenciall energy as memory of substance to get specific energy/ies?

    No.

    Potential energy is energy associated with the particular configuration of a system at a particular time. It requires no "memory".

    Yes. For example, potential energy, which comes in lots of different types: gravitational, electrical, magnetic etc. Light carries energy that is not kinetic. Electromagnetic fields carry energy that is not kinetic. The binding energy of an atomic nucleus or an atom is not kinetic.

    Depends what you mean by "connected".

    No. A ball in the air doesn't need any memory. The gravitational potential energy that it has is not a property of the ball alone, but a property of the earth and ball taken together as a system. The energy depends on the configuration of the system - namely how far the ball is away from the Earth.

    No.

    Thanks & welcome.

    Can't it be considered as a short term memory or circumstanial memoy?
    An atom taken on hill, should be having some changes due to acquiring of different position or different gravitational force(energy). In short term these changes should be changes in its motions. Ok? It also has memory to go down & get normal motions. Why this can't beconsidered as its memory in short term? Long term memory may need structural or chemical changes. Moreover energy spect or consumed can also effect energy at global/universal level in view of thermodynamic equilibrium. This can also cause changes in atoms(motions in short run)? Ok?

    Why that configuration or change in position be taken as short term memory because it can stay for some time till reversed?



    Why them matter is not called as condensed or consolidated energy Or simply potential to get energy?

    Do we have different type of potential energy in time factor i.e. short term, long term etc.?



    Is there no theory in physics that all substances are related to each other?



    Is it not a short term memory?
